Using the multiband s-f model we derive the formulae determining the Curie temperature and magnetic moment as functions of concentration x for R(1)1-xR(2)xAl2 intermetallic alloys, where R1,2 denote magnetic rare earth metals. These formulae, applied to R(1)1-xR(2) alloys (R(1) = La, Lu, Y, Zr and R(2) = Gd) give the linear dependence of the Curie temperature and magnetic moment versus x in full agreement with experimental data.
